Definitions

  • the invention relates to a cable termination unit for telecommunication, signal, control cables or the like.
  • a trough-like carrier in the interior of which the end of a cable and the cable cores emerging from the cable can be attached, with a multiplicity extending transversely to the longitudinal direction of the carrier, Terminal blocks that can be placed on the carrier and are aligned parallel to one another and have a plurality of rows of contacts, two rows of which have a stripping-free conductor connection, the contacts of one row being provided for incoming wires and the contacts of the other row of outgoing lines, in particular jumper lines, and with at least one further row of contacts for the possibility of contacting surge arresters, isolating plugs, test plugs or the like, the row of contacts of the incoming wires, viewed in cross section through the terminal block, being arranged lower than the row of contacts of the outgoing lines.
  • Such termination units see. DE-A-31 36 662
  • Such termination units see. DE-A-31 36 662
  • the object of the invention is therefore to design a cable termination unit of the type mentioned in such a way that the individual connections can be carried out easily and securely and are clearly arranged.
  • the cable termination unit should be inexpensive to manufacture and versatile.
  • This is achieved according to the invention in that the contact row for the surge arresters is provided in the connection blocks between the contact rows of different heights and in that the surge arresters extend in the space above the low row of connection contacts in the connection block.
  • This arrangement allows easy assembly, since the connection contacts for the outgoing lines are exposed and are not covered by surge arresters.
  • such an arrangement allows the possibility of making changes to patch cables even when the surge arresters are plugged in.
  • connection block can be simple in such an arrangement.
  • the gradual arrangement of the two outer rows of contacts also ensures that there is enough space for the surge arrester without the space for the terminal block with surge arrester being significantly increased.
  • a further contact row for test plugs or isolating plugs is provided between the two contact rows for the incoming conductors and the outgoing lines.
  • the row of contacts for the outgoing wires is expediently free of the magazine of the overvoltage conductors in order to be able to safely wire the already installed cable termination unit to the outgoing lines, while at the same time ensuring that an overvoltage protection is installed.
  • the individual connection contacts of the row of contacts for the outgoing lines are each designed as double contacts, so that several lines can be connected to one connection contact.
  • the installation on the cable termination unit or the wiring of the connection block is made considerably easier.
  • the connection contacts for the incoming cable core are constructed as single contacts.
  • the adjacent contacts of at least one row of contacts are each offset from one another. The inexpensive assembly for the individual connections of the contacts is retained.
  • the receptacle for the stripping-free terminations for the incoming cable cores or for the outgoing lines and / or the wiring tool for establishing a connection with connecting contacts is designed in such a way that the wiring tool is connected in two rotational positions separated by 180 ° for connection the wires and / or cables are functional.
  • Such a design of the receptacle and / or the wiring tool allows an inexpensive and time-saving connection of the individual wires to the stripping-free connections.
  • the two have a contacting slot between the contact legs of the individual stripping-free connections, the roof tip having the contacting slot being oriented in the longitudinal direction of the wires and / or lines to be connected.
  • the roof tip having the contacting slot being oriented in the longitudinal direction of the wires and / or lines to be connected.
  • the roof tip of the wires is on the subsequent copper-based conductor. While with other conductors the roof top can be turned exactly 180 °. The roof top then points away from the veins. With this arrangement, the connection between the terminal contact and the wire is made even stronger when the wire is pulled. Due to the roof-shaped design and the alignment of the roof, the boundary edges of the contacting slot are buried deeper in the metallic conductor of the wires when the wire is pulled. It is expedient for the middle contact leg itself to be roof-shaped when the stripped connection is designed as a double contact, in this case the roof tip of the middle leg is aligned in the longitudinal direction of the line or wire to be connected. Such a central roof-shaped contact leg results in secure assembly and retention of the line in the connection contact.
  • connection contact when only one connection of the double contact is occupied, the other is not hindered in its functionality.
  • the middle contact leg advantageously has a bulge for guiding in contours of the connection block. In this way, the connection contact can be easily assembled, since the connection contact can be brought securely to the correct position by the guide.
  • one of the contact legs of the contacts for the test or isolating plug is divided into two contact tongues by slitting. This subdivision results in a very safe contact making with a simple design, so that it is always ensured that this contact leg touches the mating contact with two places.
  • the chambers provided in the connection block for receiving the individual contacts are closed to such an extent that they can be poured out with grease. This avoids that leakage currents can occur at the individual contacts under unfavorable climatic conditions, which can possibly hinder the function of the cable termination unit.
  • a U-shaped grounding rail can be used in the central region of the surge arrester, the leg spacing of which can be varied to accommodate different arresters. Due to the central arrangement of the grounding rail, the magazine can now be equipped with surge arresters from both sides, so that such surge arrester magazines can be made particularly small and the wiring with the cable assembly unit is installed Can't interfere with patch cords. Due to the variable width of the earthing bar, arresters of different sizes can be used with the magazine. It is advantageous here if the surge conductors in the magazine are held resiliently against the grounding rail. Here, a melting pill that limits the heating of the arrester in the event of overvoltage contacts the arrester.
  • the spring contact leg pressing the arrester against the earthing rail touches the earthing rail after the melting pill has melted, since this leads to a safe dissipation of the overvoltage without damaging the arrester.
  • the surge arrester magazine arranged in the connection block engages with slots on the walls of the trough-shaped support with resilient tongues provided on the earthing rail, thereby ensuring a safe dissipation of the overvoltage. Furthermore, a simple assembly is provided by such a design, since by simply inserting the magazine, the connections of the arrester are grounded.
  • connection block is fastened in the trough-shaped carrier by a snap-in connection, which further facilitates the mounting of the connection block and thus the assembly.
  • a combination plug with current fuses can be inserted into the individual contacts of a row of contacts. This results in a further application of the cable termination unit. To do this additional task, it is advisable to interrupt the contact between the cable and the magazine connection to switch on the power fuse.
  • the contacts for the power fuses are advantageously separable via an opening in the lower part of the connection block. This ensures a safe replacement of the current fuse in a simple manner, since the contacts can be kept separated by an insulation blocking element which can be moved in via the lower opening, while the new current fuse can be inserted between the contacts from above. It is therefore always guaranteed that no harmful overcurrent can reach the patch cords.
  • eyelets serving for the wire guidance are provided on the side end faces of the connection blocks and are divided into a plurality of receptacles by intermediate webs.
  • contacts of the surge arresters arranged in the magazine come into contact with a bend in the connection contacts when the magazine is inserted into the connection block, the free end of the turn pointing towards the magazine, while the bends themselves are formed on a foot part of the connection contacts .
  • this ensures good contact between the bend and the contact of the overvoltage conductors, and on the other hand ensures that the insertion forces of the contacts of the magazine that occur when the surge arresters are inserted can easily be absorbed by the bends formed on the foot area without permanent deformation the turn occurs.
  • the cutting blades arranged downstream of the connecting contacts are advantageously supported directly on legs of the connecting contacts. This measure allows the cutting knife to be arranged and held securely, since the high specific pressure during the repeated wiring and cutting of the cores, if any, is absorbed by a metallic support, namely a connecting contact leg. A change in position of the cutting knife in the vertical direction is impossible even when cutting. It is advisable if the cutting knives are provided on their upper end face with a bevel forming a cutting edge, while the lower end face has an offset which serves to identify the position of the cutting edge. By cutting the cutting knife, the cutting pressure is reduced. The offset on the cutting knife allows precise alignment of the cutting edge during assembly, even visually controllable, so that the cutting edge with respect to the type final contacts can be arranged precisely.
  • the cutting knives advantageously engage in guide grooves of the connection block on their two longitudinal sides. By widening the cutting blades and forming guide grooves in the receiving contours of the connection block, stable guidance and secure mounting of the cutting blades is achieved.
  • the contact legs of the connection contacts are provided with embossments on both sides of the slot and / or the contact tongue in the region of their outer edges.
  • embossments on both sides of the slot and / or the contact tongue in the region of their outer edges.
  • the outer edges of the contact legs of the connecting contacts are lengthened, so that the two contact legs are slightly inclined to one another. This not only gives you the option of punching the contact guide slot wider - with a more stable punch knife - and embossing it to the desired narrow slot width, but also deforming it to undersize in order to obtain an additional preload compared to the wire to be connected.
  • the channel-like depressions for the connection contacts are advantageously provided with chamfers. Due to the bevels, the cable cores can be easily inserted into the channel-like depressions. In addition, the bevels offer the possibility of introducing the wiring tool in a simplified manner, so that an improvement in assembly technology is achieved. It is recommended here if the wiring tool used to connect the wires and / or lines to the connection contacts has three plate-like sections lying next to one another, the middle section protruding from the two outer sections and being able to be pushed back against the force of a spring. The protruding section in connection with the bevels enables a significantly improved placement of the wiring tool. The resilient central section is received in the handle of the wiring tool during the contacting and cutting process for the wire to be connected.
  • connection block has a bore in the area of the eyelets, into which a metal sleeve provided with a longitudinal slot can be inserted, which on the one hand comes into contact with the metallic carrier and on the other hand serves to hold a measuring plug, such as a banana plug.
  • This metal sleeve provides a simple plug connection with which the potential, e.g. Earth potential of the carrier from the terminal block, can be measured.
  • the slot extends over the entire length of the metal sleeve to generate a bias in the metal sleeve, which ensures secure mounting and contacting the measuring plug, at the same time, a rib can engage in the slot in some areas, which ensures correct use of the metal sleeve for Carrier designed.
  • the metal sleeve has a further slot in one end region, in which case both slots have a widening in this end region as well as projections that reduce the slots.
  • connection block 20 shown in FIG. 1 has a two-part housing, with an upper part 21 and a lower part 22.
  • connection block has steps 23 and 24 which are of different heights.
  • the low step carries a depression 25 on the side of the higher step.
  • An eyelet 26 is provided under the lower part 22 of the connection block 20. This eyelet is used to hold and guide cable wires.
  • Eyelets 27 are also provided on the two end faces of the connection block 20, but they have a slot 28 for inserting jumper cables into the eyelets.
  • the eyelets 26 serve to bring cable cores to the connection block 20, while the eyelets 27 receive the outgoing patch cables and holders.
  • the eyelets 27 are divided by intermediate webs 78, so that several receptacles 79 are created in the eyelet 27.
  • the cable cores to be connected to the connection contacts can be pre-sorted into these receptacles in the correct order so that they can then be switched on continuously using the wiring tool. This saves considerable assembly time. In addition, wiring errors are almost prevented.
  • an extension 29 is provided on the side end faces in the lower region of the connection block 20. This extension has a projection 30 directed away from the connection block, latching lugs 31 being provided on both sides at the foot of the projection. Projection 30 and locking lugs 31 are used to guide and hold the connection block on a carrier 63 (see FIG. 10).
  • Channel-like depressions 32, 33 are let into the upper ends of the steps 23, 24. These channel-like depressions serve to accommodate cable cores and to hold connection contacts.
  • connection contact 34 which is designed as a single contact.
  • a cable wire can be connected to this contact.
  • the contact (see FIG. 7) has at its upper end two facing lugs 35, the spacing of which is smaller than the outer diameter of the cable wires to be connected.
  • the lugs 35 form an approximately circular recess 36 at the upper end of the connection contact, which recess continues in a contacting slot 37 at its lower ends.
  • the width of this contacting slot is slightly smaller than the conductor of the cable wire.
  • an expanded slot connects to the contacting slot.
  • This slot serves to simplify the production of the connection contact, since the necessary punching tools can have a sufficient thickness.
  • connection contact 34 divides the connection contact into two contact legs 39. These contact legs are angled in such an angle that the connection contact 34 is roof-shaped in cross-section, the contacting slot 37 being designed as the center of the roof, so to speak.
  • the connection contact 34 continues, as will be shown later, in the connection block 20.
  • the channel-like recess 32 has a cutting knife 40 behind the connection contact 34.
  • This cutting knife is used to cut excess lengths of wire; the cutting knife engages with side edges in guide grooves 83 of the connection block 20.
  • This Cutting knife has an offset 82 at the lower end, with which it is supported on a foot part of the connection contact.
  • a housing recess 41 is provided at the bottom of the lower part 22 of the connection block under each of the channel-like depressions 32.
  • This housing recess serves to accommodate cable cores which are brought through the eyelet 26 to the terminal block. The cable core then leads from the housing recess to the channel-like recess 32 assigned to the recess.
  • the recess 41 is narrowed in some areas so that the cable core can be held there.
  • connection contacts 34 of stage 23 are arranged offset from one another (see FIG. 2). This transfer takes place in order to be able to maintain the necessary safety distance.
  • connection contact 42 is provided in the recess 33.
  • This contact is designed as a so-called double contact (see. Fig. 4,5 and 6).
  • the contact 42 has two contacting slots 37, the upper end of which also ends in a recess 36.
  • the exit of the recess has again been reduced in diameter by lugs 35, so that the recesses can in turn be used to hold the cable wires to be connected.
  • the double contact has a tongue 43 in its center. This tongue forms parts of the recess 36 and the lugs 35 at its upper end. The tongue is provided with a bulge 44 in the lower region.
  • This bulge serves as a guide when inserting into the housing of the connection block 20.
  • the two outer contact legs 39 are bent at an angle to each other again, while the tongue 43 itself is also roof-shaped in such a way that the half of the tongue with the first contact legs 39 is roof-shaped in cross section and that the second half of the tongue with the other contact leg is also roof-shaped (see FIG. 5).
  • the roof-shaped design in the area of the contacting slot is now arranged in such a way that when a jumper wire is connected, the connection between the conductor and the connecting contact is strengthened when the jumper is connected to it, since the tensile load attempts to convert the roof-shaped design into one plane.
  • the contact 42 in the channel-like recess 33 is also followed by a cutting knife 40, which is also held in guide grooves 83.
  • This cutting knife is also provided with an offset 82 with which it bears against a projection of the connection contact 42.
